NARRATIVE:
On 03/30/2021 shortly before 8:00 a.m., Troy Police Officer Shane Marker went to the Imperial Court area looking for Jalen T. Alexander, 19, who was wanted on Miami County and Greene County warrants. The Miami County case included allegations of felonious assault and child abuse/endangering after Alexander was accused of firing a handgun at his girlfriend's father. Marker knew Alexander was associated with a red Jeep Cherokee registered to his girlfriend, Tashaya Tipton.
.
Marker saw the Jeep running in a driveway and requested another officer before attempting to stop it after it left the residence. Alexander continued away with Tipton riding in the front passenger seat, and Marker pursued south on State Route 202.
.
The pursuit lasted approximately seven and a half minutes and covered about 11 miles, reaching approximately 120 mph. Alexander crossed center lines, traveled through intersections and nearly struck other vehicles. Police radio traffic recorded Marker saying several times that he was backing off, including because of traffic, but the pursuit was never terminated before the fatal crash.
.
A Miami County sheriff's deputy deployed stop sticks at State Route 202 and Ross Road. Alexander attempted to avoid them, but the Jeep's right-front tire was punctured. Police later said the crash occurred too soon afterward for substantial tire deflation to have occurred.
.
At U.S. 40 and State Route 202, Alexander entered the intersection against a red light and struck a Volkswagen driven by Chelsey Vollmer, 32, who was traveling to work with her 17-month-old daughter in the back seat. Alexander and Vollmer were pronounced dead at the scene. Tipton and Vollmer's daughter survived with serious injuries. Vollmer's daughter suffered fractured ribs and an enlarged spleen.
.
Police said Tipton later told investigators that Alexander saw the red light and Vollmer's approaching vehicle but made no attempt to avoid the collision, telling Tipton immediately beforehand, “If I’m going, you’re coming with me.” No gun or other contraband was recovered from the Jeep after the crash.
.
The pursuit prompted public criticism over whether an 11-mile chase reaching 120 mph should have continued. Signs placed near the crash site asked whether the chase had been necessary and called attention to the danger police pursuits pose to uninvolved motorists. Troy Police Chief Shawn McKinney maintained that Marker acted within the department's pursuit policy.
.
Vollmer's estate filed a wrongful-death lawsuit in 2023 against the City of Troy, Marker, Sgt. John Marshall, Capt. Zachariah Mumford and McKinney, alleging police should have terminated the pursuit because of its extreme speeds, traffic conditions and danger to the public. In July 2026, the Ohio Second District Court of Appeals ruled that the city and officers were entitled to governmental immunity and ordered judgment in their favor.
.
OFFICER BACKGROUND:
Shane Marker was the Troy police officer who pursued Alexander. Marshall, Mumford and McKinney were supervisory officials whose actions during the pursuit were examined in the subsequent wrongful-death litigation. McKinney testified that Alexander's warrants and police belief that he might possess a handgun justified continuing the pursuit. Troy police had conducted 12 pursuits in 2020 and terminated six of them for safety reasons.
